Outline¶

  • Focus on the Semantic Discovery and Knowledge Base backend components
  • Demonstrate mapping and linking of communities semantically
  • Integration of third party ontology and data
    • EU data infrastructure
  • Demo: Synthetic case study of the backend - linking materialsproject.org, EuroSciVoc and DOME 4.0!

Outline of the Steps¶

  • Load the ontology eco system - as basis for all data and knowldge!
  • Create fully semantic data sets (Tier1: compliant with DOME 4.0 data Set Ontology)
  • Demonstrate Visualisation and SparQL and python query

Note:¶

This work is largely based on D3.6, it extends SimPhoNy-Future into a new Package developed specifcally with DOME requirements in mind: Ontology_Manager, OntoVIS and sigraDB.

DomeDataSetfrom D3.6 is in /Users/adham/dev/dome/Ontology-matters/domeo/domeo.ttl

Visualise¶

We will be available in enhanced - interactive/modern form - on the front end with final release¶

Load the Materials Informatics Ontology (MIO)¶

  • MIO is a new top level ontology compliant with EMMO but is optimised for practical applications
  • EMMO requires heavy use of reasoners as it is built on logic,
  • This poses heavy constraints on applications, as one has to deal with complex structures, e.g., composite complex classes requiring intensive inference in real time
  • MIO is simple and focuses on practical applications, especially for software engineering perspective
In [10]:
mio=Graph(bind_namespaces="rdflib")
mio.parse("/Users/adham/dev/ontology/ontology_manager/MIO/mio/mio.ttl")
Out[10]:
<Graph identifier=N3edc34ad292d44c0b4b7245278a635b9 (<class 'rdflib.graph.Graph'>)>

Visualise¶

Advanced Visualisation and integration of ontology¶

We rely on RDFLIB like many other open source programs for RDF management, but augment it with additional tools both in house and external!

  • OntoVis, SimPhoNy-Future, Ontology Manager, SigraDB, OMI, are in house

Combine ontology from multiple resources and zoom into the data set with cross connections¶

In [12]:
# Using the power of RDFLIB it is easy to combine ontology: 
gc=dome.g+mio
# Using the new OntoVis: Visualisation and inspection is easy 
ovis = OntoVis(gc)
In [13]:

We create now a SimPhoNy-CUDS¶

Let us use EuroSciVoc as True Semantic keywords!¶

and integrate with MIO+domeES ontology!¶

  • Load the EuroSciVoc ontology (mostly individuals, but with clear hierarchy)
  • Use SPARQL to pick all the concepts that are relevant for engineering and technology
  • for the demo: Make a function to select randomly 1 to 5 such semantic keywords, and add it to the dataset.

Attain practical and real compliance, and use of European Infrastrcutre and investments.¶
